| This article is supported by the project of science and technology ministry, which name is the radioactive exploration technology and experimentation on deep mineralization information of Nanling key ore district (Sinoprob-03-01-4C).QianLishan-QiTianling region is an important mental material base in China, in this region; nonferrous metal and rare metal are enriched. Lead-zinc, tungsten, tin, uranium and other metal are rich. Because of many years mining, the mine in this area has been at the resources crisis condition. So, in order to looking for the continued resources and prolonging the lifetime of mine, relieving mine resource crisis, promoting development of mining industry. Strengthen prospecting work at deep mine and peripheral ore in this region is must be done. According with this problem in this region, in this article, we use geogas survey, combined with nuclear detection technologies about X-ray fluorescence to get the information of deep ore in this region. Provide evidence for further ore-prospecting work in this area.We carry out X-ray fluorescence on the whole drilling core of the drilling ZK12101 in HuangShaping peripheral. We get more than 800 points, obtain raw data more than 10,000. the result show that ray fluorescence has its superiority in quickly confirming prospecting horizon and ore bearing litho logy, we can quickly and directly confirm ore bearing horizon and litho logy.Combining the previous develop work in QianLishan-QiTianling area, we layout a 60km profile in HuangShaping area which lead and zinc concentration degree is high. We carry out geogas survey, A kind of sampling was used to collect geogas by accumulation, and the continuous sampling time is 30d. We get the concentrations of elements in geogas samples, including Mn, Zn, As, Bi, Li, Cd, Pb, Li, Cu, Ag, REE and radioactive elements, which were determined by instrumental neutron activation analysis. In addition, another kind of sampler was used to collect geogas fleetly. The concentrations of non-ferrous elements, noble metal elements, REE and radioactive elements in geogas samples were determined by inductively coupled plasma mass spectrometry. On the whole line, we get more than 400 points, Obtain more than 10,000 analysis data.According to the geogas survey data, there are seven anomaly areas in the whole line. The anomaly area one is known to us, anomaly area two is closed to limestone area of QiTianling rock, the other anomaly area are distributed in QiTianling granite. Clustering analysis, factor analysis and consistency analysis are used in analysis obtain measuring data. We infer that anomaly area two is the best area to bearing ore.This paper has the following features and research results:1. Follow the principle that from know to unknown, practice is the standard to test the theory right or wrong. We carry out experimental study above the known ore body. According to the result of radiation detected, the radiation detected prospecting model is established in this region.2. Analysis the data which is collect by X-ray fluorescence, in order to looking for the bearing ore strata, then providing basis to the research on genesis and deep detecting.3. The nuclear detection technology was used in QianLishan-QiTianling region on geological survey; in order to delineate the favorable prospecting target, provide the basis to the further prospecting work. |
